The journey to the moon had been the first step toward future exploration(探险) in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is millions of miles away. Traveling to the planets will be man’s next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.

Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed(确认) nor ruled out. Russians have discovered that the surface of Venus(金星) is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠) and the pressure is nearly a hundred times greater than that of the Earth’s atmosphere.

Scientists believe man may find planets which have the same conditions as those we have on Earth , but man should realize Earth will be his only home for a long time and begin to love and care for it.

63. According to the passage, traveling to the planets will be ________.

A.  much easier and even more interesting  B.  far more exciting and dangerous

C.  man’s final aim                    D.  man’s first step

64. Which of the following is Not true?

A.  Mars is nearer to the earth than the moon.

B.  The moon is much nearer to the earth than Mars.

C.  Of all the planets, Mars is the nearest to the earth.

D.  All the planets are much farther to the earth.

65. From the passage, we can guess_____.

A.  there is life on Mars       

B.  there is no life on Mars

C.  the atmosphere of Mars is not so dense as that of Venus

D.  scientists will have little hope to find the answers

66. Man can live on under the conditions of _______.

A.  much too hot surface                   B.  the same pressure as we get on earth

C.  normal atmosphere as we have on earth     D.  both B and C

The Mississippi

    The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century. The River Indians used it as a highway and as a source of food, and it was they who gave it its name—“misi” meaning “great” and “sipi” meaning “water”．When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater.  71  . From the source of the Missouri to the tip of the delta （三角洲）, it is 2, 480 miles long.

    Great rivers are likely to suffer floods. In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path. In 1938 its floods drowned or killed 200 people and made millions homeless. Today the river has largely been controlled.   72  .

    Industries have spread down some of the waterways of the delta, but otherwise the delta is a remote place, the homeland of a little colony of French Canadians that the British drove out of Nova Scotia in the 18th century. They still speak French, mixed with English, Indian, Spanish and Negro idioms. They keep to themselves, fanning the rich soil of the delta.   73  .

      74  . Pioneers who first reached its banks wondered not only where it went, but what lay beyond. In 1764 the French founded a city on the right bank of the river, and named it after their king, Louis XV. This city, named St. Louis, became the jumping-off place for the adventurous men and women who opened up the Great Plains, and the way to the Far West.

    Some 40 years earlier, at the beginning of the 18th century, the French had founded another city just above the Mississippi delta, New Orleans.   75  . New Orleans is one of the great ports of the world, and one of the greatest terminals for both sea and river traffic.

    A．It was the Mississippi that made the city what it is

    B．Levees, high banks built of earth, hold back the flood waters

    C．Therefore, as we know, it’s the third longest river in the world

    D．It is known that the“Great Water”has also been a frontier river

    E．However, they paddled up and down the Mississippi in their boats to seek their fortune

    F．The“Great Water”always remains a thread, for the streets of the city are below the level      of the river
